Just remember, if the books are on auto request, it's not really going to be "offered" to you with the normal 48 hour response time...it will be offered and auto-accepted within an hour, so make sure those books set to auto-request are ones you really want to spend a credit on now, as you may not have a chance to cancel or decline.

I have my whole wishlist set to autorequest and quite often will get up in the morning to find a couple of books have been posted, accepted and marked mailed before I even realize they've been ordered. (Which I love, because everything on my WL, I really want!)
